Officials may breach levee as Isaac storms inland

NEW ORLEANS (AP)-Louisiana officials said Wednesday they may have to intentionally breach a levee in a flooded area as Hurricane Isaac made a slow, drenching slog inland from the Gulf of Mexico and a dusk-to-dawn curfew was declared in New Orleans.

Louisiana Gov. Bobby Jindal said officials may cut a hole in a levee on the east bank of Plaquemines Parish to relieve pressure on the structure. At a news conference in Baton Rouge, Jindal said there was no estimate on when that might occur.

He said as many as 40 people are reportedly in need of rescue in the area.

Plaquemines Parish has also ordered a mandatory evacuation for the west bank of the Mississippi River below Belle Chasse, worried about a storm surge. The order affects about 3,000 people in the area, including a nursing home with 112 residents.

Officials said the evacuation was ordered out of concern that more storm surge from Isaac would be pushed into the area and levees might be overtopped.

Meanwhile in New Orleans, Mayor Mitch Landrieu issued a curfew for the city as Hurricane Isaac lashed the city on the seven-year anniversary of Hurricane Katrina's destructive arrival.

Police cars had been patrolling the nearly empty streets since Isaac began bringing fierce winds and heavy rains to the city Tuesday night. The curfew was set to start Wednesday night and would last until further notice.

Rescuers in boats and trucks plucked a handful of people who became stranded by floodwaters in thinly populated areas of southeast Louisiana. Authorities feared many more could need help after a night of slashing rain and fierce winds that knocked out power to more than 600,000 households and businesses.

Although Isaac was much weaker than Katrina, which crippled the city in 2005, the threat of dangerous storm surges and flooding from heavy rain was expected to last all day and into the night as the immense comma-shaped storm crawled across Louisiana.

Army Corps spokeswoman Rachel Rodi said the city's bigger, stronger levees were withstanding the assault.

"The system is performing as intended, as we expected," she said. "We don't see any issues with the hurricane system at this point."
